As the results below show, there aren't a lot of applications,
so far, that take advantage of dual processors. This should
change as more applications get rewritten for OS X - which
has multi-processor support built into the OS. The tests below
were carried out using XLR8's dual processor G4/500 and single
G4z/500 cards. To simulate the full range of XLR8's G4 ZIF
processor upgrades we clocked down the processors in steps,
and, in the case of the single processor MACh Velocity MPe
results, removed one of the processors from the dual carrier
card.
It is clear that the G4 does make a big difference on applications
that can take advantage of it, such as certain functions of
QuickTime, SoundJam and Photoshop, and that dual processors
can potentially cut rendering time almost
in half. The combination of both the G4 and dual processing
should provide a potent force, as we move forward with both
Mac OS X and dual or quad processor machines and upgrades.
All card configurations worked without a hitch when installed
in our Beige
G3/266, though the use of the dual processor card requires
you to disconnect the floppy drive
The tests below are from our suite of real
world application tests. These tests feature a diverse
selection of applications commonly used by the Mac community.
The test suite was designed to render an accurate and well
rounded picture of a machine's performance. All of the tests
below (with the exception of the Quake III & Cinebench
2000 tests) were timed with a stopwatch. The times are then
converted to percentages relative to our base Blue & White
G3/350 machine which is set to 100%. For all scores, higher
numbers are better. Absolute scores for most tests can be
found below this section.
**Please note: The Power Mac G4/533 is a single processor
machine
